Abstract

The invention provides a defrosting control method and device of an air conditioning unit and the air conditioning unit, and relates to the field of air conditioners. The defrosting control method comprises the following steps that a current moment is acquired; whether the current moment is within the night time period or not is judged; if yes, defrosting is conducted according to acquired on-off states of all indoor units; and if not, whether the current moment meets the preprocessing condition or not is judged, and if yes, preprocessing is carried out. According to the defrosting control method, different processing modes are adopted according to different current moments, and if the current moment meets the preprocessing condition, preprocessing is carried out so as to optimize the defrosting process in the night time period; and if the current moment is in the night time period, the working state of the air conditioning unit is refined, defrosting operation is adopted according to the on-off states of all the indoor units, so that the defrosting operation of the air conditioning unit in different working states is more targeted, therefore, refrigerant flowing noise during defrosting can be reduced, and the use comfort of a user can be improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a defrosting control method and device for an air conditioner unit and the air conditioner unit. Background technique [0002] In winter, as the temperature drops, people’s demand for the heating capacity of the air conditioner increases. However, because the outdoor unit of the air conditioner is prone to frost, the heating capacity is seriously attenuated. Therefore, if defrosting is not performed, the heating effect of the air conditioner will be reduced. Significantly reduced, thus unable to meet the user's demand for heating capacity. [0003] In the prior art, during heating operation, the four-way valve is usually used to reverse the direction, so that the refrigerant flow direction is switched to the cooling mode to defrost, so as to achieve the purpose of defrosting. However, at the moment when the four-way valve changes direction, because of the unbala...
